IPN scientist eliminates 100% human papillomavirus

Eva Ramón Gallegos, a researcher at Mexico's National Polytechnic Institute (IPN), managed in collaboration with other specialists eradicate 100% human papillomavirus in 29 patients from Mexico City suffering from this disease.

With molecular studies, IPN showed the elimination of the virus in patients treated with photodynamic therapy. This is a non-invasive technique that can be an effective way to prevent this neoplasm.

The human papillomavirus is the second cause of death for Mexican women.

"In the first part of the study, the results were encouraging when used for the women in Oaxaca and Veracruz. Using the technique in the capitals also had a very encouraging effect, allowing for more effective treatment," said specialist.

Dr. Ramón Gallegos has been studying the effect of photodynamic therapy in various neoplasms (melanoma, breast and cervical cancer) for two decades. Therefore, he clarified it in the clinical phase 420 patients have been treated with this treatment from Oaxaca and Veracruz, beyond the 29 from Mexico City infected with the human papillomavirus.

The specialist added that under the scheme for women in the capital also had a positive effect on the elimination of pathogenic bacterial strains.

Eva Ramón Gallegos explained that the therapy involves the use of a drug called aminolevulinic delta acid for the cervix, which after four hours is converted into protoporcin IX, a fluorescent chemical that accumulates in damaged cells, allowing them to be eliminated with a special laser beam. to be impregnated with it.

Therefore, the treatment in the first part of the study was used three times with an interval of 48 hours each with a radiation time according to each case and type of injury. Then, revisions were made and diagnostic studies were repeated.

The results were as follows:

  • In humans who had only the virus without lesions, the human papillomavirus was eliminated in 85%.
  • Patients who had human papillomavirus with lesions had an effect of 85%.
  • Those who had lesions without human papillomavirus succeeded at 42%.

"Unlike other treatments, it only removes damaged cells and does not affect healthy structures. Therefore, it has great potential to reduce the rate of death from cervical cancer," he said.
